Mechanical problems with the Radwaste evaporators resulted poor quality water being processed to this out fall. This water was known to have been of poor quali ty prior to p'rocessing forward, but was not acted upon due to high water inventories in Radwaste.

Once the water was discharged to this out fall tank, it could not be reprocessed, and must be discharged to the cooling Pond Blowdown line.

CORRECTIVE ACTION:

Operating personnel were notified of the need to reproces. poor quality water, instead of processing it forward. Operating personnel agreed with this, and will reprocess poor quality water. They are also attempting to correct the problems with the evaporators, which will alleviate the need for reprocessing.
